Abstract
A process for the production of a thermoplastic cured epoxy resin which is transparent to visible light, characterized by curing (A) an epoxy compound having two epoxy groups in one molecule with (B) a compound having two phenolic hydroxyl groups in one molecule by means of (C) a cure accelerator consisting of at least one compound represented by general formula (1): (1)[wherein R is a monovalent C2-10 hydrocarbon group which may have a hydroxyl group at the β position to the nitrogen atom (with the proviso that when R has three or more carbon atoms, R includes both straight-chain and branched-chain hydrocarbon groups); when R has no hydroxyl group, R has a number of carbon atoms of 3 to 10; n is an integer of 1 to 3, and m is an integer of 2 to 0, with the sum of n and m being 3; and when multiple Rs are present, the Rs may be the same or different].
